According to a familiar distinction, neuroethics incorporates the neuroscience of ethics and the ethics of neuroscience. Within neuroethics, these two parts have provoked distinct and separate lines of inquiry, and there has been little discussion of how the two parts overlap. In the present article, I try to draw a connection between these two parts by considering the implications that are raised for ethics by scientific findings about the way we make moral decisions. The main argument of the article is that although neuroscience is “stretching” ethics by revealing the empirical basis of our moral decisions and, thereby, challenging our present understanding of the dominant ethical theories, substantial further questions remain regarding the impact that neuroscience will have on ethics more broadly.
